Dear Freesurfer Folks,
I have returned to the problem of trying to extract T2 values from a T2-map using aseg & mri_segstats. When I attempt mri_segstats it only returns a small subset of the regions from aseg (see attached file). I would like to attach the T2 map but the file exceeds the 25mb limit for gmail (could I drop the file somewhere?) Could the T2 values need to be in a special format?
Thanks very much for your help.

mri_segstats, for example:
mri_segstats --seg aseg.mgz \ --ctab $FREESURFER_HOME/FreeSurferColorLUT.txt \ --i T1.mgz \ --sum T1.stats
produces a text file 'T1.stats' which has stats on each aseg struct as taken from the vol T1.mgz.

Dear Freesurfer,
I have co-registered a map of whole brain T2-relaxation time
values to
the corresponding aseg.mgz for this subject (see attached jpegs). Does a tool exist in freesurfer to enable regional sampling of T2 values from the T2-relaxation time map based on aseg?
Thanks for any thoughts.
